Hi Danny, I worked on this until 12:30 last night and finally got it to work! Thanks so much for the explanation, I looked everywhere and couldn't find much documentation on this. I was calling my "delete" a little differently than what you described, which is why it took a while to get it working, but I couldn't have done it without your help. You did a great job of explaining the concept. Thanks again. Michael On Tue, 30 Oct 2001, Danny William Adair wrote:
Hi Michael!
I think it is not wise to call delObjects() within the object to be deleted. As soon as the object is deleted, it obviously cannot be accessed anymore. But maybe that's exactly what Zope is trying to do afterwards...
Use the first version and there will be no problems. If you used a link to your "delete" method:
<dtml-in my_entries> .... <a href="delete">delete</a> .... </dtml-in>
then change them so that the parent is called: <dtml-let parent_url="my_entries.absolute_url()"> <dtml-in my_entries> .... <a href="<dtml-var parent_url>/delete?id=<dtml-var id>">delete</a> .... </dtml-in> </dtml-let>
Now, the id of the object to be deleted can be accessed through "REQUEST['id']" when you call "delete" through the link, so the "delete" method of your folder would look like:
<dtml-call "manage_delObjects([REQUEST['id']])">
Btw, if you have a look at what the management interface does, you'll see how easy it is to provide checkboxes and thus be able to delete a couple of objects at the same time.
In your loop that lists the contained entries, you would have <input type="checkbox" name="ids:list" value="<dtml-var id>"> in front of each listed object.
Then you would have a submit button that calls "delete" on the folder
<form action="&dtml-absolute_url;" method="post"> .... <dtml-let parent_url="my_entries.absolute_url()"> <dtml-in my_entries> .... <input type="checkbox" name="ids:list" value="<dtml-var id>"><dtml-var id><br /> .... </dtml-in> </dtml-let> .... <input type="submit" name="delete:method" value="delete entries" /> </form>
now you can do: <dtml-call "manage_delObjects(REQUEST['ids'])">
inside the folder's "delete" method to delete all the objects that have been selected. REQUEST['ids'] already is a list!
Just a suggestion...
hth, Danny
